|
|
I recently acquired a couple of Retro RP sets and I'm trying to find som information about them.
A search in this forum gave some answers, but RP sets don't seem to be that common.
So here comes a bunch of questions.
The PJ's are from around 1996-1998 and I found these labels on them.
Retro Data 708 OEM with HD-214 lenses
RD801s OEM with HD-114Q lenses
Retroblock D808s with HD-214 lenses
Are the Retro capabilities the same as their Barco counterparts with the same modelnumber?
For example Retro Data 708 = Barco Data 708 in terms of bandwidth, resolution etc.
Are boards interchangeable between a Retro and a Barco? (I'm a bit lazy here, I could check
some part numbers myself )
Some of have stickers with angles written on them, like 0° and 6°, so the tubes/lenses might
be tilted for some special setup. I guess is possible to undo if needed.
I read the "All about lenses" thread but there was not much information on these lenses.
I suppose all lenses are for short throw distances, or can they be used for a larger front screen?
It seems like they might work up to 100" screenwidth, but I'm not sure.
The lenses don't have corner focus knob. Will that be noticable the larger the screen is?
I read somewhere that maybe the 'Q' means corner focus via a screwdriver or something.
Are all lenses LC? The RD801s has a small hose at each lens and one hose had a hole in it and
leaked cooling (I guess). Is it easy to replace, refill this?
That was all (for now )

Mostly the answers to your questions are: YES.
All the tubes are LC, and yes, glycol leaking is common. I blew up my first retro 808s chassis because of that.
I don`t think you can FP with these sets due to the limitation of the lenses. you`d have to try it.
Some of the boards will not swap. The retros all have audio circuits, and I had one customer whose retro 708 had all sorts of mods on it. I sent him some 708 boards, but there were compatibility issues that we couldn`t resolve. I have no retro service manuals either, so I don`t know what he ever did with his set.
I still use my own Retro G808s with 49,000 hours on it. (second chassis, the first one literally exploded. Original tubes, glycol flushed once to get rid of fungus.

Well I guess I'll start leaving mine on 24/7 to catch up!
Mine are definitely the original tubes. I run both contrast and brightness well under 50, and tube emission is perfect. I pulled out the tubes in January, only the green has the slightest of 4:3 wear.

Hey you in Sweden,
the HD114 are low res - the Hd117-12 are the direct upgrade high rez small screen lens (max inofficial width about 2,6 meters, 1,8 meters official)
the big screen lens for HD114/117 is the rare Hd117-24, also high rez (2 to 6 meters).
The big screen lens swap for the HD214 is the HD215 - but both suck. So get C-Elements from the HD117 and then lenses as upgrade for 214/215.
Regards from Munich
Marc

Sorry forgot about the other questions:
Yes, with little work these are very very very fine "LC" front projectors!
